The pickup roller moves up and down to press the paper surface,
separating the paper on the top of the paper bundle and sending it
to the paper feed roller section.
separating the paper on the top of the paper bundle and sending it
to the paper feed roller section.
The paper feed roller feeds paper to the transport section to pre-
vent against double feed with the separation roller. The manual
paper feed clutch controls ON/OFF of the pickup roller and the
paper feed roller. Paper is sent to the registration roller by the man-
ual transport roller.

Tandem paper feed
a. Paper size for each paper feed tray
Paper tray 1 accepts paper of A4, 11” x 8.5”, or B5. Paper tray 2
accepts paper of A4 (11” x 8.5”) only.
accepts paper of A4 (11” x 8.5”) only.
b. Paper feed operation
1)
When the copy/print operation is started, the motor (CPFM)
and the clutch (T1PUC) are turned ON to turn ON the solenoid
(T1PUS) at the timing of paper pickup. This rotates the takeup
roller and lowers it to pick up paper.

(T1PUS) at the timing of paper pickup. This rotates the takeup
roller and lowers it to pick up paper.
2)
At the same time, the paper feed roller rotates to feed paper to
the transport section. At that time, the separation roller rotates
to prevent double feed of paper.
the transport section. At that time, the separation roller rotates
to prevent double feed of paper.
(3)
Tray paper feed
a. Paper feed front operation
• Set paper and insert the paper feed tray, and the pickup roller
falls to turn ON the paper feed tray sensor.
• The lift-up motor drives the rotating plate to move it up.
• The paper upper limit sensor turns ON, and the rotation plate
stops at the specified position.
